PCT No. PCT/GB92/01072 Sec. 371 Date Jan. 10, 1994 Sec. 102(e) Date Jan. 10, 1994 PCT Filed Jun. 15, 1992 PCT Pub. No. WO92/22885 PCT Pub. Date Dec. 3, 1992A magnified viewer capable of viewing an information card or sheet supported on a support base of the viewer. The viewer includes a magnifying lens supported above the support base by means of two oppositely disposed side portions. The side portions are each attached at one end to the support base by a first set of hinges, and at their opposite ends to the magnifying lens by a second pair of hinges. Since the side portions are pivotably connected to both the support base and the viewing lens, the user of the viewer can readily scan the magnifying lens across the information card by merely tilting the side portions from one side to another.

Description

[Detailed description of the invention] Improvements in viewer assemblies and observable materials used therein The present invention provides visual information such as a viewer and a map or route guide. Regarding the assembly of any observable materials. Furthermore, the present invention provides, for example, This can range from looking at book information, charts or cable management diagrams. flight For convenience, the invention will be described in terms of maps.

A map is a large sheet of paper that covers a large area and contains a large amount of information. or the stylization of an expanse of terrain or a complex route. It is usually used to express regional expressions. Typically these sheets are large and For this purpose, they are rolled or folded.

The map may be used indoors, for example for planning or teaching purposes. In this case, the properties of the sheet are not a direct issue. Because directly related The sheet can be easily unfolded or opened to the desired degree to provide the information This is because it is possible to do so and maintain that state. however , the map may be read outdoors as part of some sport or other activity. is also very frequent. For example, maps and maps used by tourists or other travelers. In addition to route guides such as the Subway Guide and Subway Guide, skiers can also Orienteering competitors should check the terrain map and cant. It requires a map that deals with the leeside, and it also requires a map that deals with the lee side. Medium sports stakeholders need some form of map reference. Therefore, the reduction It is common to provide maps of different lengths and emphasize different features. actually, Although some maps show the features of the desired route in a somewhat elongated form, Route markings and route markings (mostly) do not indicate the accompanying countryside on either side of the route. That's what they offer.

One problem common to all map field references is their handling. typical For example, people returning home should wear warm clothing and gloves to counteract the temperature. Usually, I have a ski striker, and I open the map to reveal the relevant part. Very difficult to fold. He takes off his gloves, but there are no pockets on his clothes. There was no pad, so he unfolded the map, revealed a suitable spot, and tried to fold it again. gloves are typically held under the arm or similarly placed in an inconvenient location while keeping. If there is some wind or such conditions, this is very This must be a difficult task, and it must be done one more time in reverse before actually starting the descent. Must be done once in a while. hikers, orienteering competitors, mountain climbers, Riders, hang gliders and a wide range of other sports have similar problems. Ru. Similar problems also occur when maps are used in the military, but conventional maps... The back side of the map is usually white, so it should not be lifted while examining the base metal. Due to the fact that if the enemy fires at a target, it can be seen as a target for enemy fire from as far away as firing range. The problem becomes even more serious.

Similarly, tourist maps can also be inconvenient to use.

Their use indicates unfamiliarity with the location and therefore invites fraud or theft. Ru.

Additionally, you will need to use some kind of tool, such as a flashlight, to refer to the map at night. It happens often. Such equipment is often used in the military or in emergency services at night. Often necessary.

Use maps or charts in confined spaces, e.g. underground or in cable ducts. Still other difficulties arise when

Therefore, you can use it in a convenient way throughout all activities that involve using Maps outdoors. It is required to provide a map or other such information for reference.

The present invention is designed to reduce the area of the map that is normally referred to in detail during active use. Partly based on the understanding that it is not the entire expanded map area of a conventional map. It's a spider. Typically referred to in detail by the user, as described above. The area is the area that would be perceivable even if all the remaining parts of the map were folded back. Ru. Such areas, for example, typically measure approximately 15X25 cm to approximately Up to A4 size. Typically, the map reference is approximately this on the sheet. Includes a series of detailed area references and examinations of size.

The present invention is a detailed map, the printed sheet of which is a folded map as described above. It is a typical size of a folded part and can be viewed at an appropriate apparent distance from the user. Magnifying vinyl for detailed maps small enough to provide magnified images for illumination It was created to provide the following. Most preferably, the viewer Configured to allow you to selectively brighten (accurately magnify) all areas of the There is.

In one aspect, the invention provides an information bearing surface and a magnifying reader assembly. (a) a relatively small scale, but a larger table of a relatively large scale; A flat surface with sufficiently high detail to carry all the information content of the surface. a surface supported and/or held in a curved viewing plane; (b) into an internal storage location near said surface, usually towards said surface or through a lens; A predetermined or selectable method that provides a perceptual image at a relatively large scale during normal observation. easily move away from the surface to the extent that it is possible, e.g., to an external viewing position. A magnifying lens supported as such, (c) at least one part of said lens and/or its support when moved to said internal storage position; a protective cover for said surface also consisting of a part and/or in said internal storage position; A protective cover is provided to cover the lens. Usually, the above table The surface is a printed map, route plan or chart.

In many, but not all, forms of the invention, the assembly described above is The attachment is a means to maintain it in a convenient position on the wearer's body, e.g. For example, the lens can be easily moved between two positions even with gloved hands. Attachment has means.

A key feature of the invention is the use of a suitable map or the like for magnification. Regarding Mano 2- The convenience of enlarging this map is that the image is a larger scale map.

The objective is that all necessary information should be included so that it is equivalent to the Discussed. However, the problem is that, for example, if you use a map with a scale of 1:100,000, So, it doesn't mean enlarging it to make it look like 1:20,000 scale. do not have.

For example, the present invention uses a map that is already at a scale of 1:20,000 to This reduces the size of the map, making it possible to create a fine and detailed miniature version of the larger scale map (effectively visible to the naked eye). printed or stamped against the background so that it is not referenceable), and then its details And by enlarging the detailed reduced version, the apparent image is the original size or a similar size. Regarding getting back to.

The present invention provides polymer or A sheet of printing paper made of polymer-coated paper or a roll made of such a sheet. of a roll or magazine (e.g. accumulation of separate or interconnected sheets) It is also possible to create an assembly in which one of the two is built-in.

In a particularly important form of the invention, the printed surface is a standard turret cartridge. (i.e. about 55 x 85 mm) in size and shape. It is in the form of a flexible sheet made of polymeric material. Such a map, on the other hand, can easily be attached to a commonly available wallet or similar device. On the other hand, it allows for security purposes on credit cards, for example. Applicable to high-precision printing technology on surfaces made of polymers, such as those used in It has a flexible shape.

Therefore, the technology for printing such materials in this suitable size is not available. and more preferably (as described below) a linear magnification of about 3× to 8×. is close to the area size of a commonly referenced map with a linear magnification of 3× to 6×. There are levels of magnification at which images can be obtained.

The device of the present invention is made of a material such as a polymer sheet the size of a Turret card. The sheet is often configured to be mounted so that it can be observed with incident light. . However, the invention also extends to implementations using transmitted light. like that Light can be provided by a simple light bulb, electroluminescent strip, beta light, etc. Matupata For reference of similar patterns, the incident light is usually sufficient even at a magnification of about 5x, for example. I found that. For reasons explained in more detail below, this is important for high-precision printing. Leads to longer life of the sheet.

The present invention also provides a relief map of the corresponding zones. It also extends to providing services. Other types of maps or similar printed materials may also be used, e.g. It can be used for underwater use and for night use.

The magnifying lens is preferably a simple lens.

However, the invention also extends to optical observation systems with one or more lenses. good In a preferred embodiment, the lens is positioned on the map, as discussed in more detail below. supported on an inclined frame and, in other embodiments, includes a slidable or other frame. supported on the frame.

Lenses can be constructed in a variety of ways and can be simple or complex, but we prefer the most preferred In a preferred embodiment, the lens is about 3x to 8x, more preferably 3x to 6x and preferably with a linear magnification of about 5x. I found it. Typical lens diameters are 10 to 30 mm. What about the lens? It is preferable to use a plano-convex lens with the flat side close to the observer's eyes. It is However, a biconvex lens with a relatively flat side on the outside may also be used. this such lenses without unnecessary distortion (particularly in certain embodiments of the invention described below). ) can be sufficiently expanded, and it is also easy to use the credit card format and expansion. Increase the apparent size of any image printed on a shape to a size convenient for focusing It is appropriate to do so.

Preferably, the viewer has a viewing position somewhat constrained in overall vertical distance from the lens. The above-mentioned map etc. are held on the observation plane. A plane that is too close is the same as a plane that is too far away. It creates a blurred image. For a lens with the above preferred magnification and aperture, the optimal plane is Normally it must be within ±5mm. For this reason, the preferred viewing plane is curved. There is. In addition, the card glue rectiwe mobility or (preferably Alternatively, expedient measures such as selective tilting of the lens may also be used, e.g. All parts of a map or surface of size can be viewed with optimal sharpness and uniform magnification. This is very suitable because it allows for careful examination.

The assembly may be implemented in a number of different wearable configurations. For example, fold It may be placed on the back of a glove or mitten in a closed position, with the other hand in the viewing position. Can be lifted by hand.

However, gloves or mittens are specialized products and cannot be used on or around the wearer's arms. It may be easier to provide the map as part of a removable unit.

One form of the above is for example the form of a removable elastic cuff made of synthetic polymeric material. , within its structure is a printed map with an enlarged portion of the upper part of the cuff located beneath it. It is foreseen that the device will have a sliding path so that it can be lifted up to the required distance. child devices such as a digital watch with other features at appropriate locations in the cuff. It's okay. In fact, maps and clocks, thermometers, barometers, alarms, compasses, etc. The combination with the available elements is a feature of the invention.

The above assembly can be used immediately for observation in any other arrangement. Wherever possible, it may be applied to elements of the user's protective clothing. For example, the position on the arm or hand. It can be worn on a neck chain or carried in a pocket, even if it is not attached. It can be realized as a sleek wallet or container.

Although it is not absolutely fixed to the body, it is always within reach and close to the wearer's head. It can be used for observation without the need to remove it from the protective headgear.

In some embodiments of the invention, the structure is readily operable by gloved hands. It is foreseen that it should be something that can be created. In many outdoor sports, Wear protective clothing of a more or less cumbersome nature, especially gloves or mittens, when skiing. used. As shown above, removing these and working with traditional maps is always In some detailed embodiments of the invention, gloves may not be worn, as this may not be practical. A simple movement of the used hand can bring the person into observation state.

Three specific embodiments of the invention that are particularly worthy of consideration are as follows.

In a preferred embodiment, the top surface has a resilient structure comprising said assembly. a cuff is provided, wherein the magnifying lens is formed from a transparent rigid synthetic polymeric material. and can move from a lower position to an upper position relative to said surface plane. The cuff has two slidable downwardly extending legs on the sides thereof.

When in use, the "legs" mentioned above will also protect against rain or snow, creating a high-detailed map. Provide dry protection.

In another particularly preferred embodiment of the invention, the invention is flat or arcuate, i.e. a support plane with a partially cylindrical profile and hinged connections at both edges of the support plane; connected and with space from that support plane and from any maps supported on it. Two upwardly foldable lenses with a lens on the free end It is implemented as a synthetic polymer structure with functional moieties. Preferably, the above fold The foldable portion is in contact with the support plane and the lens. The lens is hinged at both ends of the support plane, so that the lens It can be tilted to focus on a location, which makes it easier to scale. Other distortions can be avoided. The foldable part still offers some protection against the weather. provide.

A support plane is defined by each of the upper ends of the parallel ribs on the substrate and includes a wall portion of the substrate. Continuous as a retaining groove inside. Such a substrate is suitable for locating the surface area to be investigated. It may have a transverse rib at one end containing an entry slot. upwards One of the collapsible side parts receives the area and is positioned in the entry slot of the rib. It may itself have a lateral slot for placement.

In a third embodiment, the invention provides a lid that is easily operable into an outward position. and tilted if necessary to move towards a remote viewing position above the case. Equipped with an observation lens, the body of the case is suitable for supporting high-detail maps. Implemented as a smooth contoured wallet or such container carrying means be done. Selectively display time, temperature, barometric pressure, elapsed time, alarm status, and control data within the volume. It may include an electronic circuit that displays a path bearing or the like. The above wallet is Preferably large operating buttons for opening and selecting desired display parameters It has a smooth contour with an equally large button for it.

The preferred embodiments described in detail above may be used in convenient forms such as the maps described above. Highly detailed graphics available in credit card size and format It is something. onto a polymer-coated substrate the size of a credit card. Techniques for printing with high precision are already known and can be used to produce the above-mentioned device according to the present invention. Can be used. Most preferably, the above map or chart information is printed on one side only. The other side has an index and other information, and can be enlarged in normal size or A mixture may be used. Furthermore, as already generally stated, the lens has a linear magnification of 3x or more. 8x, such as 5x, preferably with a plano-convex lens with the curved side facing the pattern. be. The focal length of a lens with a magnification of 5x is given by the formula It is about 62mm.

Further so far unachieved effects arise from the choice of parameters proposed above. This improves the usability and service life of the above assembly. mappu If you are a user of Maps tend to deteriorate during use due to snow falling onto the surface. With this invention The maps used each have a small print size and the folding problem is overcome. Ru. Furthermore, although precision printed, it is typical both when in use and when not in use. protected. When in use, the sides of the vinyl extend to both sides of the map. Provides some protection. If the map is observed in the incident light, the The observer's head is more or less perpendicular to the map, providing additional practical protection. I will provide a. The above case or structure is used only to observe the map. and its fine details are effectively protected. It will be opened at If the map is observed in incident light, and especially on gloved hands, In this case, the fingers rest on the upper edge, providing beneficial weather protection.

Moreover, such protection during use is synergistic with adequate protection when not in use. Matsu Matsu high detail, for example, if the tape is abraded by the inner surface of a garment pocket. The problem of loss of symbols still remains. In the present invention, the structure of the viewer is Folds over and protects the surface of the tape and the precise printing on the surface. ing.

Furthermore, by providing the map in an easily referenceable format, you can check the map. The general effect is an increased propensity to do so and increased user safety.

The invention will be further described with reference to the accompanying drawings. The accompanying drawings are for each case.

FIG. 1 shows an exploded form of a first embodiment of the device according to the invention.

An integrally molded product 1 includes a base or mount 2, a side wall 3, and a pair of lens mounting members 4. and 5. The base mount 2 includes a fastening lip or clip 6 , in a preferred embodiment, has the size and shape of a regular credit card. ing.

Other features of this assembly are that each one is the size and shape of a credit card. This is a map bundle 7 printed with . For map bundle 7, you can see the pattern of the topmost map. They are held together under the clip.

As explained above, the map design is printed with high precision, and when enlarged, Regular map with regular scale for outdoor activities such as walking, skiing, cycling, etc. An image that is a part of is obtained.

In the embodiment shown, the assembly is completed with a plano-convex lens 8, but with other magnifying lenses. It is also possible to equip lenses, in particular biconvex lenses with relatively flat outer surfaces.

FIG. 2 shows the components of FIG. 1 assembled.

The lens 8 is installed with its flat surface facing outward. In this way, the curved base body and protective side walls 3, when used in field conditions with light incident on the map 7 , the general view created by the side wall 3 and the user looking down through the lens. In combination with a protected environment, the exposed maple is somewhat isolated from the effects of the weather. A viewer configured as shown in FIG.

38 and 3b schematically show an important modification of the viewer shown in FIG. figure In the viewer shown in 3a and 3b, the lens mount is located at the side edge 9. It is arranged so that it can be moved on a hinge. For this reason, always curve the map when using it. It can be manipulated to receive at substantially right angles on a oriented substrate. By this means 2 Two potential sources of error are eliminated. First, viewed obliquely through the lens Spherical aberration that causes the area to appear different and distorted from the area viewed from the front can be avoided. Second, differences in magnification and the apparent scale or scale perceived by the user. Variations in the effective distance from the lens map that would lead to distance differences are avoided. It will be done.

For card map designs of credit size, use 5 lenses with a diameter of 25 mm. It is manufactured to have a linear magnification of The apparent size of the bump is about 25 x 40 cm, and the apparent inspection distance is about 30 cm. can be observed in

This itself is a detailed one-off connection. ion) is somewhat larger than necessary.

However, because you are wearing goggles or glasses, your eyes may be too close to the lens when moving. Even if the viewer itself is used by a person who is not in a position to do so (the field of view is, for example, around the lens) (although the observed effective area is still reasonably large).

Figure 4 shows a further construction of the map shown in Figures 1.2 and 3. As mentioned above, When the tup is used, the precision printed surface provides some protection against the weather. . Similarly, when the map is folded as shown in Figure 4, the hinge 9 holds the lens. It is located between two side walls, the side walls together covering at least a majority of the map surface. child In this way, the viewer can protect the lens even when it is stored in a pocket of clothes. It is still protected against map deterioration.

However, the essential features of the invention can also be implemented in completely different configurations. Figure 5 is Exploded view of completely different embodiments of the invention in the form of bracelets or cuffs It is shown in In this embodiment, a relatively wide bracelet or cuff 10 is printed with high precision as above, preferably a common size for credit cards. It constitutes a mounting upper surface 11 which receives a small map having a rough surface. The cufflinks are It usually runs continuously around the wearer's arm and is attached with a buckle or clip. Ru. Simple cuffs with elastic closure may be used if desired. The top surface of the cufflinks is 13 A leg having a side member 13 suitably recessed so as to form a grip for wearing at part a. It is configured as a lens 12. This component is inserted into a suitable recess on the side of the cuff. , is moved by the action of the tongue piece 14 that is combined with the recess 15. As is clear, tongue piece 1 The effective width of 4 can be determined by extending the width of the cuff to each end of the map, if desired. It may be the same as the width of the map.

The illustrated device allows the user to lift the lens 12 out of the map under incident light. It functions as a viewer by looking down on the surface of the screen through a lens. Same as above , the side walls of the viewer-small assembly provide some protection from the weather. Also , the use of a precision-printed map surface that shows the user looking down through the lens. This provides additional protection for use.

The configuration of the cuff of the present invention shown in FIG. 5 allows for further modification of the device. example For example, in a recess in the cuff, for example under the map holder, you can insert a regular small battery. It is also possible to cover the battery with a simple removable lid. like this A battery is used to drive a digital timer 18 covered with a suitable transparent surface 19. can be used. Other electronic functions can also be provided if desired. One of the cufflinks Due to their general nature, either end face may be A control button is placed on the cuff to operate the micro switches 22 and 23 inside the cuff. Is possible. By making the button a suitable design, you can use it during outdoor activities. It can be used even when wearing clumsy gloves or mittens.

A further embodiment of the invention is shown in FIG. This has a completely different look, but this It has the essential features of the embodiments described in the previous drawings.

Applicant does not wish to be bound by any theory regarding its invention However, in order for the optical viewers shown in Figures 7 to 12 to be used for maps, etc., there are some design issues. It was established as an experimental problem that there is a constraint.

A regular large handheld magnifier, for example 100mm in diameter, provides a large and clear field of view. However, the magnification is not particularly high. Scan large areas, e.g. printed However, it is not suitable for use in smaller areas at higher magnifications.

On the other hand, the use of a small eyepiece lens, such as a 3 mm diameter microscope eyepiece, is It is not always acceptable to general users and requires some experience.

However, simply using lenses of intermediate dimensions, e.g. between 15 and 40 mm, While convenient for the eye, it is difficult for many purposes.

First, the depth of clear magnification is large. I can't hear it. In other words, the distance of the object being investigated from the lens falls within a relatively small range. have to wait. In the case of the present invention, for example, the diameter is 20 cm and the magnification rate is about 5×. Using a lens is useful when the distance from the lens to the object varies by a few millimeters. , there is only a difference in the magnification ratio (because the lens is too close), this is the best time to However, even if the distance is too far, the sharpness may be lost. There will be a loss. In this way, there are restrictions on the distance from the lens.

There are also constraints associated with the available field of view. In particular, cases such as those described based on the example When using lenses, the sharpest field of view is a 50-6mm diameter area on a card or other viewing surface. It is not much larger than a 0mm circle.

So far this has not been a problem.

With conventional slide vinyl lenses, the maximum sliding dimension of 35 mm is the normal diameter of a simple lens system. It fits within the precise observation area. Larger film formats actually use different I am using a viewer with a different configuration.

Similar concerns arise with postage stamp observations. Jeweler's Loupa or Magnification for Small Plants For simple lens systems such as mirrors, the desired field of view is similarly small.

However, when observing a precision printed map (as an example) up close, 3.4 or or 5x magnification, corresponds to an area of up to 250 mm diameter on a full-size map. This is only sufficient to obtain a clear field of view after magnification; less is possible. Ru.

This can only contain a small amount of information and is not practical as an independent observation card. Not.

Therefore, the present invention imposes restrictions on the observation distance, and although the means are somewhat large, they can be easily handled. 22. A means that allows selectively inspecting the precise expansion zone from the provide. Typically, a map or plan the size of a credit card (e.g. It allows general users to inspect and accurately read all parts of a subway map (e.g. subway map). Ru. In a preferred embodiment, this tilts the lens placement and tilts the viewing card. This can be done, for example, by holding it in a more constrained curved plane with a suitable correspondence. , other expedients, e.g. fixed lenses and magnifying lenses with small physical dimensions. With a ratio of 3 to 8x, for example, the precise magnification field of a static lens of 10 to 40 mm diameter is A thick (and selectively movable) knob area or the like may be adopted.

The present invention provides (a) a simple optical system that is user friendly, and (b) a small scale and precision printing system. (c) accuracy and sharpness of magnification; with respect to the distance from the lens and in different parts of the observation area to maximize the The source is the careful selection of features that constrain the region for selective inspection of It's emitting.
